TT333: Thermocouple/milliVolt Input Four-wire Transmitter

Product short description:

Universal thermocouple / millivolt input

Universal current / voltage output

12-32V DC local / bus power

The TT333 model is a space-saving four-wire transmitter that isolates and converts a millivolt or thermocouple sensor input to a proportional control signal. DC current and voltage output are both supported on a single model.

The TT333 model is a space-saving four-wire transmitter that isolates and converts a millivolt or thermocouple sensor input to a proportional control signal. DC current and voltage output are both supported on a single model. An optional DIN rail bus can deliver primary or redundant power to multiple units without wiring.

How To Prevent Temperature Measurement Errors It will give you a keen understanding of the three basic laws of thermocouples: Homogeneous materials, Intermediate Metals, and Successive/Intermediate Temperatures. It is helpful in weeding out potential sources of error in a thermocouple measurement system.

The Basics of Temperature Measurement Using Thermocouples Choosing a temperature sensor for an application is not as simple as picking a thermocouple type with a compatible temperature range. You must give consideration to the sensor material type, the application temperature range, the relative sensitivity of the sensor, the limitations of its insulation material, and its...

Description

This compact, industrial-grade isolator provides a high-voltage isolation barrier between a computer and a connected USB device.

The isolation protects equipment from electrical surges and transient voltage spikes. It also eliminates ground loop currents flowing between the PC and peripherals which can cause damage and inaccurate measurements. Additionally, isolation minimizes conducted noise from static discharge, magnetic fields, and radio frequency interference.

Acromag’s USB isolator is very easy to use. The isolator inserts in-line with the USB connection and operates transparently. No special software drivers are required. The unit receives power from the PC’s USB port and isolates that power to the connected device. High noise immunity and low radiated emissions ensure reliable data transfer in sensitive applications.

A number of high-performance features help provide convenient and dependable operation. The green LED indicates that power is being received and blinks if the connected device draws too much current. An internal jumper lets you switch from Full Speed (12 Mbps) to Low Speed (1.5 Mbps) communication. The reset button offers a simple way to reinitialize a connected device without breaking the cable connection. High-retention USB sockets keep cables securely attached under shock and vibration.
